Questions
How big is the ESP32 IoT Sensor Controller PCB?
It measures 51.5 × 48.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32 IoT Sensor Controller use?
36 parts, built around the ESP32-WROOM-32E-N4, CP2102N-A02-GQFN24R, SHT31-DIS-F and CL31B106KAHNNNE. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ESP32 IoT Sensor Controller KiCad files?
From the ehasunchy/kicad-pcb-projects repository on GitHub, at the commit this page was made from: the board is ESP32_IoT_Sensor_Controller/KiCad_Project/ESP32_IoT_Sensor_Controller.kicad_pcb and its schematic 555_Timer_LED_Blinker/Documentation/Local_Revision_2026-10-06/KiCad_Project/555_Timer_LED_Blinker.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32 IoT Sensor Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask ehasunchy before reusing the design.
